Google Deepmind Is Using AI To Build A Better Fusion Reactor

In this week’s edition of The Prototype, we look at Deepmind’s new fusion collaboration, companies stealthily building humanoid robots, a way to triple wheat production and more. To get The Prototype in your inbox, sign up here.

Google Deepmind will work with startup Commonwealth Fusion Systems to use its AI expertise to help develop fusion power, the companies announced Thursday. The research partnership builds on two capital investments that Google has made in the fusion company as well as an agreement giving the tech giant access to 200MW of power from CFS’s first fusion plant, which is on track to be built in Chesterfield, VA.

The vast demand for electricity from the data centers powering the AI boom has led tech companies to invest in fusion power, which could provide clean, nearly limitless energy — if it becomes practical (and that’s still a big if, though progress is being made). That’s a primary reason why Google, Nvidia and Microsoft have all invested in CFS.

Deepmind is no stranger to fusion. A few years ago, the AI lab worked with Swiss university EPFL to develop machine learning algorithms to magnetically contain and control the flow of plasma, a key engineering challenge for fusion reactors. The company has also open sourced its plasma simulation software.

Tech companies aren’t putting all their eggs in one basket. Google is also an investor and research partner with California-based TAE technologies. And OpenAI cofounder and CEO Sam Altman has put his own money behind fusion company Helion, which has a deal to provide power to Microsoft from its first plant, which is under construction in Malaga, WA.
